Flavin Catalysts in Organic Synthesis
Angewandte Chemie, EarlyView.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Electrophilic Catalysis in Iodosylbenzene Oxidation of Aromatic Derivatives
CHIMIA, 1986 The oxidation of activated aromatic compounds (phenols and hydroquinones) is catalyzed by BF3 or RuCl2(PPh3)3. The catalytic effect of the ruthenium is ascribed to electrophilic catalysis, due to complexation between iodosylbenzene and the Ru species ...
